Abstract
The present invention comprises a vinyl chloride copolymer consisting essentially of the copolymerization reaction product of a vinyl chloride monomer composition and at least one polyfunctional compound; said polyfunctional compound being an alkadiene of the formula: CH2=CH-(CH2)x-CH=CH2 in which x is a whole number from 1 to 25; said copolymer containing, in moles, from 99 to 99.99% of said monomer composition based on vinyl chloride and correspondingly from 0.01 to 1% of said polyfunctional compound and the process of making such copolymer.
